How to erase sector with RS232 prorocol?

  • hi,
    I am a user of the cyclone pro,the chip is MC9S08DZ48.In my factory, the cyclone pro is controlled via the RS232 protocol automatically.

    Now I have got some problem that I try to use the command $2D to program dynamic data into some address of eeprom,an error occurs, because the eeprom has been programmed in the prior process, if I want to program into these addresses which programmed before(not $FF), I need erase the sector of these addresses first.

    So in the RS232-controlled cyclone pro protocols,
    1. Is there any command used to erase sector?
    2. The function of erase sector for the MC9S08DZ48 seems as a user function, how to define and use it?

    expect for your response!
